Cutting outside corners

What happens here

Instead of assuming a perfect 90-degree angle, the crucial first step is to use a digital angle finder to measure the exact angle of the outside wall corner. The video demonstrates this, showing a measurement of 88.65 degrees, which is slightly off from 90 degrees.

Goal: Determine the precise angle of the wall corner

Do your outside corners look like this? Let's fix it. A lot of people automatically cut 245s assuming this corner is a perfect 90. But before I cut anything, I'm going to check the actual angle. This corner is 88.65. So, 88.65 I'm going to round it to 89. So, we're going to do 180 - 89 = 91. 91 / 2 = 45 1/2. This 45 1/2 is going to be our miter cut. Mark your baseboard.
